Paul’s research in information theory is largely focused on the fundamental limits of communication in multiuser settings. In addition to moving information around in the classical sense, some alternative questions arise when you consider using information to coordinate actions in a control setting. The mathematical tools needed to characterize the limits of compression in these settings are related to rate-distortion theory and require additional novel concepts as well.
